摘要： Vibration is monitored in a dual rotor engine. A first total vibration of the engine is measured during operation. Relative phase of the two rotors is then clocked, and a second total vibration of the engine is then measured during operation. First and second total unbalances are then resolved at a common response frequency from the measured total vibrations. First and second rotor unbalances are then resolved for the corresponding rotors from the first and second total unbalances. In a further method, corresponding corrective balance weights may be determined for offsetting the resolved rotor unbalances.

摘要： A vibration detector. A machine, such as a gas turbine engine, contains a rotor bearing and a gear. A nearby sensor produces a train of pulses as teeth of the gear travel past. The frequency of the pulse train indicates rotational speed of the rotor. In addition, vibration of the rotor causes the gear to orbit about another center. The orbiting causes amplitude modulation, frequency modulation, or both, in the pulse train. Detection of the modulation indicates the presence of vibration. Thus, a single pulse train, produced by a single sensor, is used to indicate both speed, and the presence of vibration.

At least one rotor blade is fabricated from a frangible material.
